Q all whom it `may concern l Be it known that I, ROBERT G. CAMBLIN,acitizen of the United States, residing at Bartlesville, in the county'of Washington -andySt-ate of Oklahoma, have invented certain new anduseful Improvements in I-Ieadlights forAutomobiles, of which the-following isa specification, reference being had 'to the accompanying drawins.

This invention relates'to j eadlights for automobiles, and particularlyto those headlightsl whereinr there Vis'fan `outer casing and laninteriorl reflector disposed within the" leasing and shiftable to castthe light either downwardly or directly forwardly or laterally.

provide a headlight on each side of the automobile, each headlightcontaining two reflectors, each of these reflectors being mounted kforadjustment so that the axis of thereflector will be either downwardlyand forwardly or directedlaterally and forwardlyand downwardly andlaterally so that one of thesey reflectors may be` directed down-`wardly 4and Vforwardly in the usual position ,of an ordinary reflector,while the'other reflector .will be directed toward the ditch side of themachine so Vthat when ,an automobile meets anothenautomobile the drivermay 'switch ofi1 the` lamp in the forwardly directed reflector andswitch on the lamp in the laterally directed reflector to thereby.prevent the glare from the first named lamp from 'striking in the eyesof the oncoming motorist. j j j v i further 'object isy to `provide aconst-ruc- 'tion of this character in which either lamp is capable ofadjustment so thateither lamp .may be used as the ordinary forwardlydirected headlight and the other reflector may be used for casting thelight laterally and forwardly toward the ditch side of the machine. j

. A still further object in this connection is vto provide a headlighthaving the two reflectors and two lamps, as stated, these lamps beingrelatively adjuustedv so that at anytime the driver'desires to `see theside of the road or a vehicle on the right side of vthe ro-ad, it isonly` necessary to switch off the driving lights, as they may beturned', and switch ron the laterally directed lights.

Another object accomplished by my inventonis to .away `with mechanism`which The general object of thev invention is to e must be adjustedbythe driver at the time when he desires to take the glare fromanoncoming motorists eyesfor desires to direct the` light to the side ofthe road by providingreflectors which, while they may be adjustedwhenever desired,are adjusted. and then leftin their adjusted-position.`Other objects have to do with the details of,construction,whereby thereflectors are supported within the outer vhousing and whereby they areadjusted. f My invention is illustrated in the accompanyingdrawings,`wherein:-- j

Figure 1 is a'frontelevation of a headlight constructed in accordancewith my invention;

Figure 2 Figure 1; f

Figure 3 is a horizontal sectional view on the line 3 3 of Figure2; i

Figure is atop plan View of light shown in Figures 2 and' 3;

Figure 5 is a perspective view of one of the clips26.

Y Referring to these drawings, and particularly to Figure 2, it will beseen that I yprovide a lamp housing 10which, as shownin Figure 1, is,generally speaking, elliptical in form or elongated verticallyy andwhich is provided with a glass pane 11` extending across the entireheadlight and supported in ,is a section on the line 2 2 of the head- 4aframe 12, this frame having hinges 13 or construction of this charactermay be used j and I do not wish to be limited to any particular meansfor mounting this elongated body upon an automobile, it beingunderstood, however, that there are two of these housings orl bodies 10,one on each side of the machine. l

The housing 10` is preferably divided through its middle by ahorizontally extending wall 14 which does not extend quite to the pane11, thus dividing the lamp housing into two compartments. In 4eachcompartment there is arranged a parabolic rekHector 15therear end ofthis reflector being formed with a socket 16 to receive the base oftheusual incandescent lamp 17. Electrical connections 18 extend outwardfrom this lampandout through the .back of the housing .'10, being'suitably insulated from the housing.l The forward endofA each reflectorLlt) is illustrated as being rounded or formed with a bead 19, andengaging against this bead at the upper and lower edges of the reflectorare springs 20, these springs bearing against small curved' plates 2lwhich approximately fit the bead 19 to afford a flat bearing surface forthe springs 20. The outer ends of the springs 20 bear against a flange22 extending inwardly from the hous ing l0, against which flange thepane 1l also bears.

For the purpose of adjusting the reflectors either into a position wherethe beam directed from the reflector is cast laterally and forwardly orcast straight ahead, I provide, as illustrated in Figure 2, theresilient ears, designated 23, which are attached to the reflector l5against the upper and lower walls thereof in any suitable manner, theseears projecting outward and forward and then nearly straight forward.Passing through each ear is an adjusting screw 2,4: which carries uponit a set nut 25. Mounted upon the wall of the housing l and of thepartition let opposite the two ears 23 is a spring clip 26 which isslotted, as illustrated in Figure 5,- and which is somewhat curved,thisspring clip bearing against the ear 23. The screws 2st beingdisposed in the slots 27 of these clips 2G act as pivots upon which eachreflector may be turned to throw the light laterally, these pivots beingdisposed in a vertical plane so that the reflector may be turned uponthese vertical pivots, the springs Q0 yielding, of cour-se, to permitsuoli movement of the reflector. The vlamp is held in this oscillatedposition by means of the lugs and clips illustrated in Figure 3. By thisfigure it will be seen that each lamp is provided upon its side wall, asdistinguished from the upper and lower walls, with an angular ear 23,while the housing is provided with the clip 28 formed in the same manneras the clip shown in Figure and longitudinally slotted, A screw 29Apasses through this ear 23. and through the slot of the clip 2S andcarries upon t'the'nut 30.

It will be obvious now that by rotating one nut 30 in one direction andreleasing the other nut that the reflector' will be resiliently held inthe dotted line position shown in Figure 3, that is tilted upon. itspivots 24.1, S0 that the axis of the reflector is directed forwardlyandlaterally, the ears 23 on the two sides ofthe reflector slipping overthe faces of the spring clips 28, while the screws engage the inner faceofV the housing 1.0. Thus the retlector is held in plaee laterallytilted. It it be desired to tilt the refleotor vertically, the screws-29 .are loosened, the releetor is tilted with its arie .downward andforward so that the upper edge of the refleotor presses the 2.0, the,Sprngfl at the lower of the reflector expande and the screws 24 aretightened so as to engage the partition 1l and the housing 10 to holdthe device in this set position, the screws 2l) under thesecircumstances acting as pivot screws.

In order to adjust these reflectors as desired, the reflectors will bedrawn out of the housing, then the adjusting screw on one side or theother will be tightened and the other adjusting screw loosened, thereflector put back within the housing, and the reflector will focus ordirect its light either to one side or the other or either up or down.The springs 20 will act to hold the reflectors pushed back se that thescrews will be at the rear ends of the slots 27 and thus the reflectoris held rigidly in place by the pressure of the springs. Sonie cars havethe aprons or fenders projecting some distance out in front so thatunder these circumstances the lower reflectors could not be used fordirecting the light toward the right side of the road and in that casethe upper lights are used for passing and the lower lights for driving.It is for this reason that I have made both the upper and lowerreflectors adjustable so that either may be used for driving and eithermay be used for passing.

Most of the headlights on automobiles are unhandy to focus, that is todirect. lt is uccessary to use a wrench and unscrew a few nuts and boltsand pry the headlights around. These reflectors can be pulled right outof the housing, then the nuts loosened or tightened a little on one sideor the other, and the reflectors put back in place and everything isadjusted. The conductors passing from the lamps will, of course, beconnected to any ordinary switch whereby the lower lamps may beconnected in circuit with a source of energy or the upper lampsconnected in a circuit with a source of energy, this switch beingmounted upon the dash board or upon the steering wheel as desired.

lith this construction there is no danger of blinding the oncomingmotorist nor at the same time is there any necessity of diniming thelamps. The lamps are always in adjustment so that one pair or the o1 hermay he used as circun'istances direct. l
